To all whom it may concern:

Be it known that we, SIx'ro GOMEZ and EMILIO Sana, subjects of-the King of Spain, residing at Contreras, D.. F., Mexico, have invented certain new and useful Improvements in Decorticating-lvla chines, of which the following is a specification. I

This invention relates to decorticating machines, and has for its object to provide a novel construction .and combination of parts,; producing a new operation, and

heightening its efficiency. for the purpose of peeling orthreshinggand cleaning the membrane-:01 thin skin which covers the roots andstalks, and the bark on the branches of trees.

broken away to showa portion of its interior. Figs. 2 and 3 are elevations of opposite sides't'hereof. Fig, 4 is a view-showing sectionaldiagrams of several modified forms of corrugations.- Fig. 5.is a detail longitudinal section through the cylinder, removed. and, Fig. 6 is a plan View of one of the rollers, removed.

Referring to these figures, thefra'mework of our improved machine embodies two 1011-. gitudinally extending side standards 1,

u-hich are'braced and connected in spaced relation, by upper cross-bars 2, and lower cross-bars 3. Projecting outwardly from one of the standards 1, is 'a pair of parallel supporting arms 4, provided with transversely apertured extremities 7 formingbearings for a shaft-'5, to which rotatory v,motion is transmitted, from any suitable source (not shown) through its'pulley 6.

Upon the shaft 5 is secured an eccentric sheave 9 around which extends the box-end 10, of a forked connecting rod 11, said rod and its box-end being in separable parts and connected at 12, by a taper pin or the While our invention may, without modifi-' like. The opposite end of rod 11 is in the form of a yoke 13, the extremities of which engage a grooved hub 14:, attached to, or forming part of the cylinder 15, and. with said cylinder, splined upon a shaft 16, by keys 1?, which shaft is journaled transversely of the standards 1, in bearings 18. The cylinder 15 is thus adapted for rotatory movement with,'and sliding movement upon, its shaft 16, by means of the connections stated. A worm-gear 8 secured upon the opposite 'end of the driven shaft 5, to its pulley 6, imparts movement to a worm wheel 19 upon a shaft 20, journaled transversely through the standards 1, in bearings 21,

' fixed in supporting arms 22, extending longitudinally from the same ends of the side standards 1, and which may form a part thereof. To the opposite end of shaft 20 .is secured asprocketwheel 23, which is connected, by a sprocket chain 25, too sprocket Wheel '24 upon the adjacent end of shaft 16, whereby to rotate the cylinder 15. At the same time. sprocket chain 25 passes over and actuates a sprocket wheel 26 secured upon the adjacent end of a shaft 27 jour'naled across the supporting arms 22, in bearings 28, between shafts 20 and 16. This latter shaft 27 also has a pair of sprocket wheels 29, one adjacentea-ch of the supporting arms 22, over which are trained sprocket chains 30, extendingalso about sprocket wheels 32 of a shaft 83, 'journa'led transversely between theextremities of supporting arms 22, in bearings"34. The'chains .30 are connected atintervals byslatsx31,

and thus form an endless conveying belt for feeding material to the cylinder"15.

Upon each of the side standards 1, adjacent the periphery of cylinder 15, is bolted a forked or bifurcated bracket 35,. and these brackets support between them, the'-= shaft of a roller 36, thus arranged above the feed belt and in the path of the material being fed thereby, whereby to'prevent the undue crowding of material against the cylinder. Thisroller is loosely supported within the bifurcated extremities of the brackets 35, and is vertically movable therein to vary the distance between-itself and the belt.

About the upper portion of the cylinder 15 are disposed a series of spaced corrugated rollers 37 arranged in an are adjacent the periphery of saidcylinder, and concentric therewith. said rollers being independently ing frames 39, one at each end of the cylinder and above each standard 1, and connected by transverse rods ii) and 41. Thus these frames may slide as a Whole, carrying the rollers 37, with respect to the cylinder 15, upon rails 42 transversely upon and between standards 1 forwardly and rearwardly of said cylinder, and are actuatedto move longitudinally, in a contrary direction. to the similar movement of cylinder 15, as heretofore explained, by'rods 43 extending thereto from box-pieces 4.5,the said boxpieces being disposed upon eccentric sheaves 46 secured upon the main, driven shaft 5. It will thus be A evident that material placed upon the feed belt, will be conducted beneath the feed-regulating roller 36 and upon and against cylinder 15, upon the surface of which it is carried around inside of the series of corrugated rollers 37, which are set in rotative motion thereby. In this manner thematerial is relieved of its skin or bark, both by the rotative action and the relative longitudinalmovement of the cylinder and rollers, and isdischarged from the opposite'side of the cylinder upon plate 457,

theskin or bark which adheres to the cylinder or'rollersbeing Washed down through I of corrugationaboth of the cylinder 15 and rollers 37, and it will be understood the especial shape of these corrugations will desea ire pend, upon the class of material being operated upon.

We claim:

1. In a machine of the character described, the combination of a rotatable and longitudinally movable corrugated cylinder, rotatable corrugated rollers disposed, in a longitudinally. movable series, about, and movable toward and away from the periphery of, said cylinder, means for rotating said cylinder, and means to simultaneously move said rollers and said cylinder longitudinally. 4

2. In a machine of the character described, the combination of a supporting,

" frame, a corrugated cylinder, rotatably and-1 longitudinally .movably mounted therein, a

frame disposed over said cylinder and slide able upon said main frame longitudinally of said cylinder, rotatable corrugated rollers idly mounted in said'last named frame, in an arc about the periphery of the cylinder con centric therewith, said rollers being movable in. their said frame to and from said cylinder, and means for rotating said cylinder SIXTO GOMEZ.
